ABSTRACT:
A general purpose, microprocessor-based printer utilizing a thermal printhead graphic dot matrix features the capability of accepting either digital or analog data from a host system or device and or printing in either data logging, textual, or strip chart recorder format. In addition to preprogrammed alphanumeric character sets, the printer controller can print any symbol or shape adaptable to a dot matrix that may be specified by data transmitted from the host system. An analog input section of the printer is provided for applications where the host input data values to be graphed are not available in digital form. The analog input section further includes selectable chart paper speed settings, a chart input range selector, zero positioner, and a visual low paper indicator.
